Science and Maths Films/Videos, Museum, Publication and Posters :

A walk through mathematics!  A film for a wide audience! Nine chapters, two hours of maths, that take you gradually up to the fourth dimension. Mathematical vertigo guaranteed! Background information on every chapter: see "Details".

http://www.newton.ac.uk/wmy2kposters/index.html  During World Mathematical Year 2000, a sequence of posters designed at the Isaac Newton Institute for Mathematical Sciences was displayed month by month in the trains of the London Underground. The posters were designed to stimulate, fascinate  even infuriate! But most importantly that they bring maths to life, illustrating the wide applications of modern mathematics in all branches of science  physical, biological, technological and financial. They are also available for sale — http://www.secureserveruk.com/macommerce/product_info.php?cPath=30_32&products_id=100
